Is the redhead on The Mentalist the same as the one on That ‘70s Show?

—Raymond Guinn, Napa, Calif.

No. Amanda Righetti, 29, who plays Grace Van Pelt on CBS’s The Mentalist, never appeared on That ‘70s Show. The Utah-born, Nevada-raised actress’ other TV credits include K-Ville, North Shore, Reunion and The O.C. Donna, the redhead on That ‘70s Show, was portrayed by New Jersey native Laura Prepon, 32, who is now blond and starring on NBC’s Are You There, Chelsea?
